Inkcazo
I-molecular seeve dehydration skid sisixhobo esibalulekileyo ekucoceni igesi yendalo okanye ekulungiseni igesi yendalo. I-molecular seeve yikristale ye-alkali metal aluminosilicate enesakhiwo sesakhelo kunye nesakhiwo esifanayo se-microporous. Xa igesi yokutya equlethe amanzi amdaka idlula kwi-molecular seeve bed kubushushu begumbi, amanzi amdaka kunye ne-mercaptan ziyafunxwa, ngaloo ndlela kunciphisa amanzi kunye nomxholo we-mercaptan kwigesi yokutya, kufezekiswa injongo yokuphelelwa ngamanzi kunye nokususwa kwe-sulfurization. Inkqubo yokufunxwa kwe-molecular seeve idla ngokwenziwa kubushushu obuphantsi kunye noxinzelelo oluphezulu, ngelixa ukuvuselelwa kwe-desorption kwenziwa kubushushu obuphezulu kunye noxinzelelo oluphantsi. Phantsi kwesenzo se-high high, clean and low pressure regeneration gas, i-molecular seeve adsorbent ikhupha i-adsorbate kwi-micropore kwi-regeneration gas flow de inani le-adsorbate kwi-adsorbent lifikelele kwinqanaba eliphantsi kakhulu, kwaye linamandla okufunxa amanzi kunye ne-mercaptan kwi-feed gas, kufezekiswa inkqubo yokuvuselelwa kunye nokurisayikilisha ye-molecular seeve.
Indlela yokuhluza i-molecular luhlobo lwendlela yokuphelelwa ngamanzi emzimbeni ngokunzulu, edla ngokusetyenziswa kwinkqubo yokwahlulahlula i-condensation kumaqondo obushushu aphantsi, njengenkqubo yokubuyisela i-condensate yegesi yendalo (NGL) kunye nenkqubo yokuphelelwa ngamanzi emzimbeni ekuvelisweni kwegesi yendalo enyibilikisiweyo (LNG). Ukongeza, ukuphelelwa ngamanzi emzimbeni kwi-molecular sieve kukwasetyenziswa ekuvelisweni kwegesi yendalo ecinezelweyo yepetroli yeemoto.
Ukuphelelwa ngamanzi emzimbeni ngesihluzo se-molecular kusebenza kakhulu kwezi zihlandlo zilandelayo:
a. Apho iqondo lombethe wegesi yendalo kufuneka libe ngaphantsi kwe -40 ℃.
b. Ifanelekile ukulawula indawo yomphunga we-hydrocarbon kwigesi yendalo enoxinzelelo oluphezulu.
c. Igesi yendalo iyasuswa kwaye icocwe ngaxeshanye.
d. Xa igesi yendalo equlethe i-H2S iphelelwa ngamanzi emzimbeni ize inyibilike kwi-glycol, iya kubangela ukukhutshwa kwegesi yokuvuselela.
e. Xa i-LPG kunye ne-NGL zifuna ukususa i-trace sulfide (H2S, CO,COS, CS2, mercaptan) ngaxeshanye, kufuneka zisuswe ngexesha elinye.
Itshati yokuhamba
Ii-adsorbers zebhedi ezizinzileyo zisetyenziselwa ukukhupha amanzi emzimbeni ngesihluzo se-molecular, ngoko ke iyunithi kufuneka ibe nee-adsorbers ezimbini ubuncinane, enye ikwinqanaba lokukhupha amanzi emzimbeni, enye ikwinqanaba lokuvuselela nokupholisa. Xa umthamo weyunithi mkhulu kakhulu, inkqubo ye-multitower nayo ingalungiselelwa.
